So this game came to me non-working and it was pretty busted up. Its been completely shopped and all switches have been inspected/gaped/cleaned. Score reels have also been disassembled and cleaned. Once I had the game all put back together I did an initial start-up to work out any other closed contacts, bugs, or issues. First I added some credits manually as the coin mechs do not work. Then I plugged it in and I push the start button. Heres where it gets wonky....the game accepts the credit-boots-goes dark.... then takes another credit-boots, goes dark and....continues to do this until there are no more credits.
Ive never seen this before. If anyone has seen this symptom before, any help on where to inspect first would be greatly appreciated.
